Intel Core i7-5650U vs Intel Core i7-5557U

Intel Core i7-5650U

► remove Intel 5650U

The Intel Core i7-5650U is an ULV (ultra low voltage) dual-core processor based on the Broadwell architecture, which has been launched in January 2015. In addition to two CPU cores with Hyper-Threading clocked at 2.2 - 3.2 GHz (2 Cores: 3.1 GHz), the chip also integrates an HD Graphics 6000 GPU and a dual-channel LPDDR3-1866/DDR3L-1600 memory controller. The Core i7 is manufactured in a 14 nm process with FinFET transistors.

Compared to the Core i7-5600U, the i7-5650U features a lower CPU base clock, but integrates a somewhat faster GPU.

Architecture

Broadwell represents the "Tick" in Intel's Tick-Tock model, which means a shrink of its predecessor Haswell. The new 14 nm manufacturing process with three-dimensional FinFET transistors allows not only improvements in energy efficiency, but also a significantly smaller die size fit for more compact packages and devices.

Further advantages result from the revised microarchitecture of Broadwell. Due to its improved branch prediction, bigger buffer sizes (1500 instead of 1000 entries in the L2 TLB) and other tweaks, the performance per clock has been increased by more than 5 percent over its predecessor. There are also some new instruction set extensions designed for cryptographic applications.

Performance

Thanks to its improved architecture, the Core i7-5650U is about 5 - 20 percent faster than the slightly lower clocked Core i7-4650U (Haswell, 15 W) and matches the Core i5-4288U (Haswell, 28 W). Thus, the CPU has sufficient power even for demanding applications and multitasking.

Graphics

The integrated HD Graphics 6000 offers 48 Execution Units (EUs) clocked at 300 - 1000 MHz. Similar to the CPU core, the GPU architecture (Intel Gen 8) has been thoroughly revised for improved performance-per-clock. In addition, the GPU benefits from faster memory speeds up to LPDDR3-1866 (Haswell: DDR3-1600). We expect the HD Graphics 6000 to be significantly faster than the former HD Graphics 5000 (40 EUs), part of the Haswell generation. Nevertheless, demanding games as of 2015 should be playable only in low or medium settings.

Broadwell is the first Intel chip to fully support DirectX 11.2 as well as OpenCL 1.3/2.0 and OpenGL 4.3. Video will output natively via DisplayPort 1.2 or HDMI 1.4a. However, the new HDMI 2.0 standard is not officially supported.

Power Consumption

The i7-5650U is rated at a TDP of 15 W (cTDP Down: 9.5 W) including the graphics card, memory controller, VRMs and the integrated chipset. Therefore, the CPU is suited even for small ultrabooks 11-inches and greater.

Intel Core i7-5557U

► remove Intel 5557U

The Intel Core i7-5557U is a fast dual-core processor based on the Broadwell architecture, which has been launched in January 2015. With a TDP of 28 W, the CPU is suited for medium-sized ultrabooks and notebooks, whereas smaller devices will use more power efficient ULV models such as the Core i7-5600U (15 W TDP). In addition to two CPU cores with Hyper-Threading clocked at 3.1 - 3.4 GHz (2 Cores: 3.4 GHz as well), the chip also integrates an Iris Graphics 6100 GPU and a dual-channel LPDDR3-1866/DDR3L-1600 memory controller. The Core i7 is manufactured in a 14 nm process with FinFET transistors.

There are also some new instruction set extensions designed for cryptographic applications.

Performance

Thanks to its improved architecture, the Core i7-5557U should end up slightly faster than the Haswell-based Core i7-4610M (37 W). Thus, the CPU has sufficient power even for demanding applications and multitasking.

The integrated Iris Graphics 6100 offers 48 Execution Units (EUs) clocked at 300 - 1100 MHz. Similar to the CPU core, the GPU architecture (Intel Gen 8) has been thoroughly revised for improved performance-per-clock.
